The Purpose of the CompletionThe well completion is the installation that enables production of fluids in a safe and efficient manner.

Ideally, the lowest cost completion (considering both initial and operating costs) that meets the demands placed upon it for the well life.


Reservoir Management ToolThe choice of completion concept is dictated by:

The reservoir model and operator’s drainage strategy.– Horizontal wells– Single zone/multiple zone– Co-mingled production/flow control– Pressure maintenance

Reservoir properties.– Open hole/Cased hole completion– Sand control measures– Stimulation– Artificial lift

The physical and chemical qualities of the fluids.– Completion metallurgy– Elastomer qualities– Deposits/Scale– Chemical injection

Other development considerations.– Expandable tubulars– Future well interventions– Well trajectory– Intelligent Wells– Multilateral wells
